語源
英語の原文（Wiktionary）
From Middle English seryows, from Old French serieux, from Medieval Latin sēriōsus, an extension of Latin sērius (“grave, earnest, serious”), possibly ultimately from Proto-Indo-European *swer- (“heavy”). (If this root is correct, cognate with German schwer (“heavy, difficult, severe”), Old English swǣr (“heavy, grave, grievous”). More at swear, sweer. However, see sērius for an alternative derivation of the Latin.)
